Transmitter instrument
Pressure (differential pressure) transmitter

Overview

The DX series pressure (differential pressure) transmitter uses imported high-quality diffused silicon and ceramic pressure sensors as measurement sensitive components. It uses a dedicated integrated module and achieves fine compensation for liquids, gases, and liquids through fine temperature, zero, full range, and non-linear compensation. Accurate measurement and transmission of pressure changes of steam and other media. To achieve the ideal monitoring of industrial and mining enterprises, scientific research institutes and other departments on parameters such as pressure and vacuum in various places.

Features

★ Dedicated V / I integrated circuit, fewer peripheral devices, high reliability, simple and easy maintenance, small size, light weight, and convenient installation and debugging.
★ Aluminum alloy die-casting shell, three-end isolation, electrostatic plastic spray protective layer, durable.

★ Two-wire 4-20mADC signal transmission, strong anti-interference ability, long transmission distance.

★ LED, LCD, pointer three indicator head, the field reading is very convenient. Can be used to measure various viscous, crystalline and corrosive media.

★ High accuracy and stability. In addition to the imported original sensor, which has been corrected by laser, the comprehensive temperature drift and non-linearity of the whole machine in the operating temperature range are finely corrected. Therefore, the non-linearity is small and the temperature stability is good in the operating temperature range.

★ Dedicated V / I integrated circuit, fewer peripheral devices, high reliability, simple maintenance, small size, light weight, and convenient installation and debugging.

★ Aluminum alloy die-casting shell, three-end isolation, electrostatic plastic spray protective layer, durable.
